T 0 aZZ whom it may concern:

Be it known that l, VVILLIAM SUMMER,

a citizen of the United States, residing at Peoria, in the county ofPeoria and State of Illinois. have invented new and useful Improvementsin FVire-lWorkin Machines, of which the following is a speclficatlon.

This invention has reference to certain new and useful improvements inwire workmachine as l have reference to and for pur-.

poses of illustration and disclosure I'have incorporated into thisapplication certain of the parts or devices shown in said patent.

()ne of the objects of the present invention is to improve theclutch-controlled mechanism included in the feeding means for the stayfeed wire.

A. further object of the invention is to provide a stay wire feedingmechanism for feeding alternately a long stay wire and a comparativelyshort stay wire whereby, a fence fabric may be manufactured havingalternately arranged long stay wires extendin;- from. one selvage ormarginal wire to the other selvage or marginal wire, and comparativelyshorter stay wires extending from one selvage or marginal wire to a.certain intermediate strand or line wire of the fence fabric. A fence soconstructed combines a field and hog fence in. the one fabric.

The invention has for a further object to connect the intersections ofthe stays and longitudinal strand wires by means of suitable wire tiesthe mechanism for feeding the tie wire stock from which said wire tiesare severed including means for feeding the tie wire stock to apredetermined number of the intersections of each succeeding long andshort stay wires included in the fence fabric, and other means forfeeding tie-wire stock to a predetermined number ofthe intersections ofonly the long stay wires included in the fence fabric. In other words,the mechanism for feeding tie-wire stock to the intersections of theshort stay wires will opcrate with the placing of not only the shortstay wires across the fence fabric, but also with the placing of thelong stay wires across said fabric and in timed relation thereto, whilethe mechanism for feeding tie-wire stock to the intersections of thelong stay wires with a predetermined number of the longitudinal strandwires will operate only at the intervals of placing said long stay wiresacross said fence fabric, and in timed relation thereto.

Like characters of reference denote corresponding parts throughout thefigures.

In my former Patent No. 1,093,578, to.

which reference has been made, a feature of the inventive idea was theintermittent clutch controlled feeding means actuated by mechanism,which, when it acted upon the stay feed wire, started said stay feedwire at a slow speed, gradually increasing until the momentum of thewire reached its maximum speed, and gradually decreasing until thecomplete stay length had been fed, the highest speed of the wire beingattained at the point when one-half of the desired length of stay hadbeen fed. This feature of invention is included in the pres entimprovements, or rather, the present improvements in the mechanism forfeeding alternately long and short stays is included in the means forfeeding the stay wire in the manner just previously stated,and'associated with said stay wire feeding means, is an improvedmechanism for feeding tiewire stock from which the wire ties aresevered, used for connecting the intersections of the stay and thestrand wires.

In the drawings, I have shown my improved stay feed wire mechanism andtiewire stock feeding means applied to that type of wire fabricatingmachine employing die mechanism for clenching wire ties around theintersections of the stay wires with the intermittent longitudinalrunning or strand wires, and coilers for wrapping or winding the ends ofthe stays around the marginal or selvage wires, with the exception thatthe upper ends of the short stay wires are connected to a certainintermediate strand wire by wire ties the same as is used for connectingthe intermediate body portions of the long and short stay wires withintermediate strand wires.

The machine is illustrated in a general way for the purpose of showingthe application of my invention thereto, and reference may be had to theSommer Patent No. 1,078,702, dated Nov. 18, 1913, for detailed views ofthe die mechanisms and coiling means such as is used in the machineherein disclosed. These details form no part of the invention herein,but merely cooperate in forming a complete fabricating machine.

It will become apparent that my improvements, as herein described andclaimed, may be applied to fabricating machines other than the kindherein illustrated, and I do not wish to be confined to the applicationof the invention to a machine such as shown.

The framework of the machine comprises in part the base members 1, theuprights 2 supporting the table 3; the standards 4-, 5, and 6, and thecross piece 7. The parts designated 1, 2, 5 and 6 are duplicated uponopposite sides of the machine and on the part 1 is supported theplatform 8 on which an operator may stand.

9 designates a drive shaft and 10 a timing shaft, both of which aresuitably journaled in hearings on the uprights 2. The driving shaft 9 isadapted to receive its power from some suitable source, such as a lineshaft or direct drive from a motor, and it in turn is adapted to operatethe timing shaft 10 through gear wheel 11 on the timing shaft (see Fig.3), which will mesh with a gear wheel on the timing shaft, not shown.

14 designates a crank shaft suitably journaled in the frame and on saidcrank shaft is a sprocket wheel 15 engaged by a sprocket chain 16 whichis driven by a sprocket wheel 17 on the timing shaft 10, said sprocketchain passing over an idler 18 carried by the upright 4-. It will beobserved that the driving shaft '9, when in operation, transmits motionto the timing shaft 10 and it in turn drives the crank shaft 14 throughthe sprocket chain 16 and sprocket wheels 17 and 15, respectively.

19 designates a wrapper shaft journaled in suitable bearings at the rearend of the machine, and said wrapper shaft 19 is driven from the crankshaft 14 by means of a nae/res? nism, and as stated, reference'may behad to the Sommer Patent,- No. 1,078,702 for details of the preferredform of structure. The mechanism for feeding the tie-wire stock to thewire connecting mechanism is material, forms a part of the present invention, and will be hereinafter more particularly described.

24tdesignates the end coilers, one for each of the selvage or marginalwires of the fence fabric, and associated with each of said coilors isa. cutting and depressing mechanism 25, although the stay feed wirefeeding mechanism when properly adjusted for the feeding of the staywires is such that the cutting mechanism at the far side of the machinefrom the in-feed of the stay feed wire is not necessary, and only thecutter mechanism at the in-feed side ofthe machine is necessary, wherebya stay length my be severed from the stay feed wire. The details of thiscutting and depressing mechanism are clearly shown in the Sommer PatentNo. 1,078,702. In operation,the cutting mechanism will sever a staylength C from the stayfeed wire B, and the depressing mechanism willdepress the ends of the stay Wire 0 down onto the coilers 24 in positionto be engaged by the pins of the coilers for wrapping or coiling theends of the long stay wires around the selvage or marginal wires, andone end of the short stay wires around one of said selvage or marginalwires.

The strand wires A, which are fed from reels, spools or other suitablemeans, not shown, pass preferably around a roller 27 on a spindle 28 andup through suitable openings in the table 3. The wires Awhich serve asthe marginal or selvage wires pass up through the coilers 24:, and thewires A, sewing as the intermediate running or strand wires, passthrough the die mechanism 23, as shown in Fig. 3.

The stay feed wire B which may be fed from a bundle, spool, or in anysuitable man ner, passes through the straightening rollers, referred togenerally as 30, and thence between the intermittently driven frictionfeed wheels 31 and 32, and leaving said feed wheels, passes throughsuitable guides adjacent to the cutter and depressor 25 across thecoiler or spindle 24: and through the die mechanisms, as shown in Figs.1 and 3. The said feed wire 13, as shown, passes between the frictionfeeding wheels. 31 and 3:2, which engage the wire to feed it endwiseacross the machine. These feeding wheels may be grooved to receive thewire B, or not, as may be desired. The feed wheel 31 is the drivingwheel of the feed, and the wheel 32 is the driven wheel. In other words,when power is applied to the wheel 31, it will impart movement to thewheel 32 through the engagement of such wheels with the wire B which isfrictionally held be tween the same. The wheel 31 is carried on a shaft33 which has a relatively fixed position with reference to the shaft 34on which the wheel 32 is carried, and the shaft 34: is journaled in aframe 35 fulcrumed at 36,

and spring means 37 engaging the forward end of the frame 35 yieldinglyholds the wheel 32 in frictional engagement with the wheel 31; theobject of which is, to allow the wheel 32 to move relatively to thewheel 31 to accommodate the various sizes of said feed wires B which it.may be desired to use in the fabric.

@n the shaft 33 carrying the wheel 31 is also carried a gear wheel 37,said gear wheel 37 and feed wheel 31 being suitably connected so thatwhen movement is imparted to one, such movement wil-lbe concurrently andsimultaneously imparted to the other. The gear wheel 37 meshes with amuch larger clutch controlled gear wheel 38. The gear wheel 38 is ofthat construction, best seen in Figs. 1 and 4c, wherein said wheel hasthe internal circumferential friction clutch-engaging face 39, and saidgear is further provided with the enlarged depending hub 4:0, said hubbeing journaled on a bushing 41 carried on a vertically disposed tubularcasing 42 suitably carried by the upright 2, shown in Figs. 2 and 4-.

4.3 designates a tubular shaft which has a bearing in the verticalcasing 4.2, see Fig. i, said casing 42 having the lower and upper innerbushings 4 1 and 45 in which the tubular shaft 43 has a bearing; saidtubular shaft 43 having the plugtG at its lower end and the similar plug47 at its upper end, which serve as hearings in which is carried andthrough which movesthe vertically movable stem 48, which at its upperend and above the bearing 4L7is secured in the hub 19 of the wheel 50having the peripheral friction face 51 adapted to have a frictionengaging relation with the clutch-engaging face 39 of the gear wheel 38.The rim and the hub of the wheel 50 are connected by the arms or spiders52, two or more of which are provided with the tubular bosses 53 inwhich are secured rods or stems 54, for purposes to be explained. On theupper end of the tubular shaft 43, and within the gear wheel 38 andbelow the body portion of the wheel 50,

is a plate or disk-like member 55; said 3 plate or'dislr-like memberbeing secured to vided with two or more bosses 56 in which I the lowerends of the rods or stems 54 are carried and movable, so that when saidplate or disk-like member 55 is rotated through and by means of thetubular shaft 43, such movement will in turn be imparted to the wheel 50through the connections between said wheel and said plate or disk-likemember, described. When the wheel 50 is raised through the movement ofthe vertical stem 48, which said movement is very slight, it will inturn elevate the rods or stems 54, without disengaging said rods orstems from said plate or disk-like member 55. From the foregoingdescription, it will be observed, that if the stem 48 is raised, it willin turn elevate the wheel 50, disengaging the friction gripping surfaceon the rim of the wheel 50 from the frictional clutch engaging surface39 of the gear wheel 38, bringing about an inoperative relation betweensaid wheel 50 and said gear wheel 38. Upon the stem 48 being lowered,the wheel 50 will in turn be. lowered, moving the friction grippingsurface 51 of said wheel 50 into impinging relation with the clutchgripping surface 39 of the gear wheel 38, whereby if the tubular shaft43 is rotated, such rotative movement will be imparted to said gearwheel 38 through the wheel 50 and the plate or disk-like member 55. Thewheel 50 is moved from friction clutch-engaging relation with the gearwheel 38 to its disengaged position, by the upward movement of stem 48,as just described, and when said stem 48 is raise'd,it is moved againstthe tension of a spring 57 carried on the upper end of rod 58, (seeFigs. 2 and 4,) and disposed between washers 59, the lower of whichbears against the hub of the wheel 50, and the upper of which is held inposition by means of the nuts 60 on the end of the rod 58. This rodextends down into the vertically movable stem 48' a suitable distanceand is secured to a transversely disposed stem 61 passing through slots62 in the wall of the stem 48, and the'opposite ends of the stem 61secured in the walls of the tubular shaft 43. Thus it will be seen thatas the stem 48 is raised, it will contract the spring 57 and as soon asthe means for raising the stem 58 is released to allow the stem toreturn to its lower or norgear wheel 38. v

The means for rotating the tubular shaft 43, as will be described, issuch that said tubular shaft is rotated alternately, first, in

one direction and then in an op osite direction. When said tubular sha tis rotated in one direction the plate or disk-like member 55, the wheel50, gear wheel 38 and the feed wheel 31 will rotate concurrently andsimultaneously through and by means of the connections described; butwhen the said tubular shaft 43 is rotated in an opposite direction, thegear wheel 38 and the feed wheel 31 with which it is geared, areinoperative by reason of the separation of the clutch engaging faces 51of the wheel 50 and 39 of the wheel 38 resulting from the raising of thestem 48, in manner described.

On the lower end of the tubular shaft 43 and below the casing 42 (seeFig. 4) is carried a gear wheel 63 and said gear wheel is in mesh withand adapted to be driven alternately in opposite directions by therackbar 64. Said rack-bar is movable in the guide 65, coincident withthe gear wheel 63 and at its inner end said rack-bar 64 is sooured to aslidable head 66 having, preferably, a dovetailed connection with andmovable on a bar 67, (see Fig. 2), said bar 67 supported by a bracket 68at one end secured to the part 1, and at its opposite v end secured uponan arm 69 attached to the upright 4. It is obvious that any movementwhich is imparted 'to the rack-bar 64 will be in turn imparted to thegear wheel 63 and the shaft 43 to which said gear wheel is attached.When the rack-bar 64 is moved forward, or in the direction indicated bythe arrow in Fig. 2, the stem 48 is in its lowermost position, being inthat position shown in Fig. '4, and the clutch engaging face 51 of thewheel 50 is in clutch engaged relation with the clutch engaging face 39of the gear wheel 38 and said gear wheel will rotate concurrently andsimultaneously with the wheel 50, the tubular shaft 43 and the gearwheel 63. Such movement will also be imparted to the gear 37 and in turnto the feed wheels 31 and 32 for the purpose of projecting the stay feedwire B across the machine preparatory to the operation of the cutter anddepressor 25 for severing a stay length C. When the rack-bar 64 is movedin an opposite direction to that just described, mechanism will bebrought into play for elevating the stem 48, which will in turn raisethe wheel 50 and by such movement separate the clutch engaging surface51 on the wheel 50 from the clutch engaging surface 39 on the wheel 38,and stop the rotation of said gear wheel 38. The alternate forwardmovement of the rack-bar 64 and the operation of the gear wheel 63 issuch that only sufficient movement will be imparted to the gear wheel38, to rotate the feed wheels 31 and 32 to feed the stay feed wire asufficient distance for delivering long and short stays C of the properlength, and that immediately upon the gear wheel 38 as es? being stoppedin its rotation, the cutter 25 will be operated to sever a short or along stay length C from the stay feed wire B. The rack-bar actuatingmechanism includes adjusting means, as will be described, for regulatingthe stroke of the rack-bar to insure the feeding of long and short staysof proper length.

Pivotally connected at with the slidable head or blook 66 is a pitmanbar or rod 71 and said bar or rod has a pivotal connec' tion at 72 witha plate 73 slidably carried on a casting 7 f keyed on the crank shaft14. The plate 73 has a substantial dovetail connection with the casting7 4.: (see Fig. 11), and such connection while permitting of a slidablerelation between said plate and said casting, holds the plate trueduring its movement back andforth on said casting. To provide for thepivotal connection between said pitman bar or rod 71 and the plate 73,said plate has a stem 75 projecting there from, formed with twoshoulders 7 6 and 7 7 On said stem between the shoulder 76 and the bodyof the plate 7 3, is carried a collar 78 having a threaded stem 79, andon said stem 75 between the shoulders 7 6 and 77 is carried the end ofthe pitman bar or rod 71, whereby a pivotal relation is produced betweensaid pitlnan bar or rod 71 and said plate 73. That ortion of the stem 75between the shoulder 7 and the extreme outer end 75 of said stem isthreaded as at 80 to receive a nut 81 for holding the collar 7 S and theend of the pitman bar or red 71 in operative connection with said stem.The casting 7a is formed with a hub or hearing portion 82, about whichencircles a segment gear 83, said gear being stationary while thecasting 74: is rotatable. This segment gear 83 is in juxtaposition to acam plate 8-l, and said cam plate and said segment gear wheel 83 arebolted or otherwise suitably secured to the standards 5 and 6. On therear end portion of the casting 7 at and located on the outside facethereof is rotatably carried a plate 85, said plate having a hub 86.Journaled in said casting, and having a bearing in said hub 86 of theplate is a hub 87 of a gear wheel 88, said gear wheel and said plate 85being connected so as to rotate together by means of the'bolt 89 passingthrough said plate 85 and gear wheel 88 and with a nut 90 secured on theend of said bolt, the plate 85 and the gear wheel 88 being suitablyrecessed to receive the head of the bolt and also the nut as best seenin Fig. 13. Secured to the rear face of said gear wheel 88, by bolts orother suitable means, a plate 91 having the friction bearing surfaces92, (see Fig. 16). The gear wheel 88 is so disposed on the rear face ofthe casting 74: that during each complete rotation of the casting 74:with the crank shaft 14, the gear wheel 88 will intermitsilt tentlyengage with the teeth of the segment gear 83 and rotate the plate 85one-half revolution. The engagement of the teeth of the. gear wheel 88with the teeth of the segment gear wheel 83 will take place duringonehalf revolution of said casting 74, and during the remainder of thecomplete revolution of said casting 7d, the friction bearing surfaces9:2 on one side of plate 91 will enand ride on the cam surface of theplate 84;, holding the plate 85 in the position just previously moved bythe intermeshing of the teeth on the gear wheel 88 with the teeth of thesegment gear wheel 83. The gear wheel .88 is provided with diametricallydisposed master teeth 93 to impart the initial movement to said gearwheel 88 and the plate 85, when said master teeth move into engagementwith the first tooth of the seg ment gear 83.

The pitman bar or rod 71 which actuates the gear wheel 63 through therack-bar 6d, is rcciprocated through the rotary movement imparted to thecasting 7% by the rotation of the crank shaft i l, and the length ofthestay wire C is determined by the position of the plate 73 and its stem 75 (to which is pivotally connected the pitman bar or rod 71) withrespect to the axis of the crank shaft i lby means of which the plate 73is rotated. In other words, the closer to the axis of the crank shaftlet is carried or positioned the stem 75, the shorter will be the strokeof the rack-bar 6d, and the farther from the axis of the said crankshaft 14 is carried or positioned the stem 75, the greater the stroke ofthe raclebar 64-. A short stroke of the rack-bar 64: will produce ashort stay wire C and a long stroke of the rack-bar 64 will produce along stay wire C.

Tn my former Patent, No. 1,093,578, the pitman bar or red, to which isconnected the rack-bar, is shown connected with a crank arm through andby means of which the pitmanbar or red is reciprocated, and said pitmanbar or rod has an adjustable connection with said crank so as to shortenor lengthen the stroke of the pitman bar or rod and with it therack-bar. The adjustment includedin such driving mechanism, in my formerpatent, was only for the purpose of regulating the length of the staywire with each difierent type of fence to which the machine wasadjusted. That is to say, all stay wires were of the. same length,reaching from one selvage or marginal wire to the other selvage -ormarginal wire, and the only necessity for adjusting the stroke of therack-bar would be in the event of a change in the height of the fence.In the present machine the stroke of the rack-bar must be changed withevery other stay and this change must be done antomatically so that witheach alternate stroke of the rack-bar a longand a short stay will be fedinto the fabric. I accomplish the alternate feeding of a long and ashortstay wire by automatically changing the position of the plate 73with its stem 75 on the casting 74 during each revolution of the crankshaft 14. That is to say, as the casting 74 is rotated with the crankshaft 14 to impart a reciprocal movement to the pitman rod or bar 71,the gear wheel 88 will mesh with the intermittent gear wheel 83,imparting a one-half turn to the plate 85 and through connectionsbetween said plate 85 and the plate 73, which I shall now describe, theposition of the plate 7 3 with its stem 75 may be moved closer to orfarther from the axis of the crank shaft 14 whereby a short stroke ofthe rack-bar 64 may be made for the purpose of feeding a short stay wireC, or a long stroke of the rack-bar 64 may be made for the purpose offeeding a long stay wire C.

Having a dovetailed connection with and slidably adjustable on the plate85 is a head 94, said head formed with an extension 95 to .which issuitably connected one end of a threaded stem 96, the opposite end ofsaid stem passing through a bearing plate 97 secured to the end of theplate 85. The end or the threaded stem 96 is squared as at 98,

- whereby by means of a suitable tool the threaded stem may be operatedto adjust the position of the head 94 on the plate 85. Suitablyconnected with the head 94 is a threaded stem 99; and said stem 99 andthe similar stem 79, previously referred to, have a threaded relation ina tubular nut 100, and on said threaded stem 99 is carried a tubular nut101 serving to lock the position of the threaded stem 99 in the nut 100,and on the threaded stem 79 is a tubular nut 10:2 serving to lock theposition of said threaded stem 79 in the tubular nut 100. In each ofsaid nuts 100, 101 and 102 suitable openings or perforations areprovided for the insertion of a suitable tool for adjusting the threadedstems 79 and 99 relatively to each other to regulate the position of theplate 73 on the casting 74, and the position of the head 94 on the plate85, such adjustment increasing or decreasing the length of the stay wireC, when necessary to insure the long stay wire reaching from one selvageor marginal wire of the fence to the other, or from one selvage ormarginal wire to a certain intermediate strand wire of the fabric.

I will now describe the means for elevating or lifting the stem 48 toseparate the clutch, engaging surface 51 of the wheel 50 from the clutchengaging surface 39 of the gear wheel 38 when the rack-bar 64 is movedin a direction opposite to that indicated by the arrow on the rack-bar(Fig. 2). On the cam shaft 10 (see Fig. 2), there is carried a wheel 103having the engaging surfaces 104 and 105, the latter acting as a camsurface and leading and merging into the surface 104 at points 106 and107. Adapted to engage and roll upon the surfaces 104 and 105 of wheel103, is a roller 108 carried by an arm 109, which said arm is fulcrumedat 110 on a bracket 111. The arm 109 is formed with a neck 112 carryinga stem 113, which said stem is normally in axial alinement with the stem48 operatively carried in the tubular shaft 43, and said stems 113 and48, re spectively, are connected by a loose joint 114, (see Figs. 2 and4). The object of such loose joint is to provide for moving the stem 48when the arm 109 is operated on its pivot 110, and also to allow theshaft and stem to rotate without disturbing the actuating means for saidstem. When the roller 108 is engaging and traveling upon the surface 104of the wheel 103, the arm 109 is in a position permitting the stem 48 toassume its lowermost position, being that position shown in Fig. 4,where the clutch engaging surface 51 of the wheel 50 is in clutchengaging relation with the clutch surface 39 of the gear wheel 38. Whensaid roller 108 is engaging and traveling upon the surface 105 of thewheel 103, the lower end of the arm 109 has been swung outwardly on itspivot 113, elevating the neck 112, and raisin the stem 48 to cause thewheel 50 to be raiser separating the clutch surface 51 of said wheelfrom the clutch engaging surface 39 of the gear wheel 38 and stoppingthe rotation of said gear wheel. When the rack-bar 64 is moved in thedirection indicated by the arrow on said bar in Fig. 2, the roller 108is riding on the surface 104 of the wheel 103 and the clutch engagingsurface 51 of the wheel 50 is in clutch engaging relation with theclutch surface 39 of the gear wheel 38; immediately upon the rack-bar 64reaching the limit of its forward stroke, whether it be for a short or along stay, the off-set portion 106, where the surface 105 of the wheel103 merges into the surface 104 of said wheel, engages with the roller108, operating the arm 109 to elevate the stem 48 which will cause thewheel 50 to be raised, separating the clutch engaging surface 51 of saidwheel 50 from the clutch engaging surface 39 of the gear wheel 38, andthe parts will be held in this position until the rack-bar 64 is movedbackward the limit of its stroke and is again ready to be movedforwardly, when the roller 108 will ride off of the surface 105 at thepoint 107 onto the surface 104, the arm 109 being oscillated throughsuch movement and through the expansion of the spring 57 which wascontracted during the separation of the clutch engaging surfaces asaforesaid, causing the stem 48 to be moved downwardly carrying with itthe wheel 50, through the connections previously described, causing theclutch engaging surface 51 of the wheel 50 to enter into clutch engagingrelation with the clutch engaging eeann? surface 39 of the gear wheel38, when said gear wheel may be rotated through the driving connectionbetween the tubular shaft 4:3 and the plate or disk-like member 55 withsaid wheel 50, previously described.

The surface of the wheel 103 is pref? erably formed by the arch-shapedwings and 116, (see Figs. 5 and 6,) which are adjustably attached to therear face the wheel 103, so that the peripheral face of said sectionsmay be brought together or moved apart, while yet at the same timeextending or retracting the surface 1G5 for the purpose of adjusting orregulating the move? ment of the arm 109, to conform to the stroke ofthe racl=:bar64:, or to conform to the movement of any other parts ofthe mechanismwith which the same has a timed relation. 1 r i It will beunderstood from the foregoing description, that the timing shaftlO has aone to one relation with the crank shaft 14; that is to say, the timingshaft 10 is geared to make one revolution with each revolution of :thecrank shaft 1 1, and vice versa, so that with each. stroke of the pitmanbar or red 71 and the rack-bar 64,

whether the mechanism is feeding a long stay wire Cor a short stay wireG,the wheel 103'on said timing shaft 10 will operate in timed relationthereto to actuate the mechanism for separating the clutch engagingsurfaces between wheel 50 and the gear wheel'38, and permit such partsto reengage at proper intervals of time to actuate thefeedingllltZCllHJllSl'l'l forprqeotmg either a long stay wire C or ashort stay wire C across the fence fabric. It is obvious that throughthe mechanism described for operating the pitinan bar or rod 71 from thecrank shaft 14, that durlng the movementof said pltman bar or rod 71 andsaid rack-bar 6 1 to feed a long stay wire C, such parts will moverelatively faster than they Wlll move during the feeding of a short staywire (I, and

-\vl1e!;lie1' operating to feed a long stay wire between the wheel 50and the gear wheel 38.

will be actua-tedso as to insure the separation of such clutch engagingsurfaces after the feeding of each long and short .stay

wire C. p i

The long and short stay wires C where they intersect with theintermediate strand wires A of the fence fabric are connected theretoby. means ofstaple-like tie-members D. 'li'hose tie-members are firstsevered from tie-wire stock E, said tie-wire stock being intermittentlyfed to each ofthe intersections of the long and short stay wires F or amore detailed denism, reference may be had to the Solnmer Patent No.1,078,702. 'However, by reference to Figs. 17 to the feeding mechanismfor the tie-wire stock may be seen,

such as usedon "that side of the machine for feeding the tie-w1re stockfrom which the staple-like tie-wire sections are made for the upperportions of the long stay wires C, where they cross the upper series of1n- BGIIDSClltttG strand wires A, (see Figs. 3and 21) and. with slightmodifications the mechanism shown in Figs. 17 to 20 is used on the otherside of the machine for feedlng the tie-wire stock from which thestaplelike sections are severed used for connecting the lower portionsof the long stay wires nally and in opposite directions, (see Figs.

8 andQl), but this arrangement in no wise affects the symmetry of thefence or its practicability.

Having reference to the tie-wire stock feedingmechanism for both sidesof the machine, 117 designateiis a driving shaft on which carried aplurality of friction driva ing wheels 118. This shaft 117 isintermittently operated by means of a pawl 119 pivotally connectedbetween plates 120 loosely carried on said shaft 117, and to said platespivotally connected a member 121 which in turn has pivotally connectedthereto a pitman bar or rod 192, and said pitman bar or rod is r ablyconnected to one end of a lever 123 fulcrunaed-at on the bracket G8,'andsaid lever at its opposite end carries a roller 125 ridnig against andadapted to I be'o tierated by the cain wheel 1% carried on theouterendoftne time shaft 10. Thus, SJl'th each revolutlon of the timing shaft 10,

the pitman bar or rod 122 will be reciprocated,causin;,2; the pawl 119to engage with a teeth of a ratchet wheel 127 keyed or otherwisesuitably secured on the drivingshaft 11? between. the'plates 120, androtate said shaft to feed in the tieavire stoclrE. The feeding of thetie-wire stock E is accomplished through the feeding wheels 118 and aser s of feeding wheels 128 which coiiperatc therewith, said l'--mentioned feeding wheels carried ona driven shaft 129 and internallygeared thereto through the internal gears geared together by means ofthe intermeslring gears 132 and 133, best seen in Fig. 2.

r The feeding wheels 128 are adapted to be yieldingly forced intocooperative relation with the feeding wheels 118 for the purpose offeeding the tie-wire stock E, or one or more'of said feeding wheels 128may be released and allowed to run loose when it is desired to cut outthe feeding of any one or more of the tic-wire stock wires E. This isaccomplished by rotating each feeding wheel 128 in a friction bearingblock 136k, and engaging each bearing block is, a bar 135" which maybecaused to hear more or less against the bearing'block 134, by means ofthe adjusting screw 136. The mecha 'nism which'l have just described forfeeding the tie-wire stock is substantially the same for bothsides ofthe machine.

It is necessary, however,v to operate the driving shaft 117 on thel'efthand side of the machine, looking at Fig. 3, when each long and'shortstay wire has been fed across the fence fabric, because the tie-wirestock E fed by means of the feeding rollers 118 and 128 on this side ofthe machine, is used to supply the tie-wire stock for the formation andattaching of staple-like tie-wire members for that portion of the longstay wires attached to the corresponding intermediate strand wires A towhich the short stay wires are attached; whereas, the tie-wire stock fedby. the. feeding rollers 118 and 128 on the opposite or right-hand sideof the machine, looking at Fig. 3, is only fed when a long stay wire Chas been fed across the fence fabric, and such tie-wire stock is usedfor supplying the wire from which the staplelike tie-wire members areseveredused for connecting the upper portions of the stay wires C to theintermediate strand wires A across; which the short stay wires C do notextend, In other words, the driving shaft 117 is partially rotated witheach alternate movement ofthe corresponding shaft 117 on the other sideof the machine, and with every other rotation of the timing shaft 10. Iaccomplish this through the provision of an additional ratchet toothedwheel 137. This wheel is loosely carried on the driving shaft 107, andpreferably upon an extension ofthe'ratchet toothed wheel 127, (see Fig.20). Theratchet toothed wheel 137 is much larger in diameter than theratchet 7 other toothof the ratchet toothed wheel 127 and suchengagementwill occur when the pawl 119 enters a deep tooth 138 on thewheel 137, but when said pawl enters a shallow tooth on said ratchetwheel 137, itwill be held from engagement with a tooth on the wheel 127,although the pawl 119 may move and with it will move the ratchet toothedwheel 137 as will be understood. The pawl 119 for this side of themachine is provided with an extension 139 to permit it to haveengagement with the teeth of the ratchet toothed wheel 137 (see Fig.18). It is obvious, therefore, that with each alternatemovement of thepawl 119 having the extension 139, or when the pawl 119 engaging with ashallow tooth on the ratchet wheel 137, said pawl will not engage with atooth on the ratchet wheel 127, and that no movement will be imparted tothe driving shaft 117, although the ratchet wheel 137 will rotatethereon, but that when said pawl. 119 enters a deep tooth 138 of thewheel 137, said pawl will engage with a tooth on the ratchet wheel 127and impart a partial rotation to the driving shaft 117 for feeding inthe tie-wire stock E.

The ratchet toothed wheel 137 is secured to or forms a part of a sleeve140, which is carried on the sleeve extension of the ratchet toothedwheel 127, and for yieldingly and frictionally holding said sleeve 14:0and ratchet toothed wheel 137 in operative positionrelativcly to theratchet toothed wheel 127, a threaded stem 111 is secured into the endof the shaft 117 and on said stem is carried a bearing plate 1-l2adapted to engage the end of said sleeve 140, and said bearing plate 1&2is adjustably and yieldingly held in this position by means of a spring143 coiled about the stem 142, said spring hearing against the plate 1&2and against looking and adjusting nuts 1 14.

The tire-wire stock E is fed to the machine from suitable reels orspools over a roller 1 15 and through tubes 146, which said tubes for aportion of their length extend transversely across the machine and thendiagonally to the wire connecting mechanisms 23, as best seen in Fig. 3.

In Fig. 22 is represented a piece of fence fabric comprising tenlongitudinal wires, two of which form'the outside marginal or selvagewires and the remainder of which comprise the intermediate strand wires..1 standard field fence with ten longitudinal wires would constitute aten bar forty-seven inch fence. This fence with the long and short stayswould combine, as previously stated, a hog and a field fence, thatportion of the fence connected by the short stay wires including sixlongitudinal wires corresponding to a six bar twenty inch fence. Thefigure illustrates the progressive order in which the short and longstays are attached and the manner of attaching the bill same, and thefeeding in of the tie-wire stock from the opposite sides of the machine,and as shown, one short stay has been attached, a long stay .is in theact of being applied, together with the tie-wire stock fed totheintersections of said long stay and intermediate strand wires, andindotted lines is shown the successive step in feedingia short staywire, after the feeding of each long stay wire.

',l"he end coilers through which the outside i'narginal or selvage wiresof the fence pass, are driven from the timing shaft 10 by means of the.bevel gear wheel 1%? interineshing with the bevel gear pinions 148 onthe lower ends of said coilers.

On the opposite ends of the timing shaft 10 are carried cam wheels 14:8and engaging and riding on the surfaces of said cam wheels are rollers150 carried by levers 151,

' fulcrumed at 124: on bracket 68, and to tlfe rear end of each of saidlevers 151 are pivotally connected bars or rods 152 for oper ating apullout mechanism, not shown. The pull-out mechanism to which the barsor rods 152 are connected is substantially such a mechanism as is shownand described in the Sommer Patent 1,078,702, the same being adaptedwhen moved to intermit tently advance or feed the strand wires A throughthe machine, and. adjusted to move said strand wires the distance atwhich it is desired to place the stay wires from each other to providethe proper spacing between the stay wires on the fabric.

In my former Patent No. 1,093,578, there is shown, described and claimeda mechanism for operating the rack-bar which would feed the stay wire,starting at a slow speed and increasing to the maximum speed, andslowing down to a complete stop, whereby a predetermined and givenlength of stay wire is fed, without any waste, thus avoiding thesevering of short pieces from the stay wire C after the wire is fed.This is accomplished by the use of theparticular mechanism shown in thatpatent for driving the rack-bar from the crank shaft. The mechanismheresubstituted for driving the rackbar from the crank shaft will notony permit of the feeding of the stay wires in the manner just stated,but is also adapted, as described, to alternately feed a long and ashort stay, embodying in such mechanism the feeding of the stay wire,starting at a slow speed and increasing to the maximum speed and slowingdown to a complete stop.
